Sierra Filters Work Greatby Michael from Prattville, Alabama on June 13, 2011

I switched to the 10 micron fuel/water separator filter in 2008 and have had great service from them. I change them every 50 hours and keep spares on the boat. I've never had a clog and I don't have issues with the 10% ethanol fuel I'm running. Great price too!

This is labeled as a replacement for the Mercury 35-802893Q, but when received the specs reflect it is a 21 Micron filter! NOT the 10 Micron filer I need. I had looked for the specs on-line before ordering and they were not listed. The 10 Micron P/N is 18-7945 according to the West Marine website.

water filterby James from Texas City, Texas on April 16, 2012

i have always had a great experience dealing with i-boats and have always gotten quality products for a low price and these water filters for my boat are no exception. great filter for a great price !!!!

With gasoline now contaning 10% ethanol, removing water from the fuel is important. Ethanol attracts moisture from the air, and moisture in the engine is bad news. I've used Sierra fuel/water separators for years, and never had any such related problems with water. They should be changed yearly, more frequently if you run more than the average.
